What Is an Electromechanical Relay?
An electromechanical relay is a switch that controls electrical circuits by opening and closing contacts with electromagnet force.
Comprising a coil, contacts, and an armature, these relays operate by generating a magnetic field as current flows through the coil, attracting the armature to close the contacts and complete the circuit. The cessation of current allows a spring to return the armature and contacts to their original positions, thus breaking the circuit.
Valued for their compactness, affordability, and reliability, electromechanical relays serve in household appliances, automotive systems, industrial machinery, and telecommunications. Their advantages include compact design, cost-effectiveness, excellent insulation, simplicity, and high reliability. The ability to support various contact configurations underscores the importance of selecting a relay that suits the specific requirements of its operating environment.
